Hemos visto una afluencia de informes de syzkaller donde un programa BPF adjunto a un punto de seguimiento desencadena una violaci\u00f3n de la regla de bloqueo al realizar un map_delete en un mapa de calcetines/sockhash. No pretendemos apoyar este escenario de uso artificial. Ampl\u00ede la verificaci\u00f3n de tipo de programa permitido del verificador existente para actualizar sockmap/sockhash para cubrir tambi\u00e9n la eliminaci\u00f3n de un mapa.
